CATALAO, João P; MARIANO, Sílvio J; MENDES, Victor M  and  FERREIRA, Luís A. Short-Term Operational Planning of Hydroelectric Power Systems. Inf. tecnol. [online]. 2006, vol.17, n.3, pp.149-155. ISSN 0718-0764.

A study was made on the problem of short-term operational planning for hydroelectric power systems. Consideration was given to multiple reservoirs in a cascade and the effect that the variation of the head has in the operating efficiency. This non-linear effect coupled with the cascaded hydro configuration tends to produce a complex problem of large dimension. For its resolution an optimization method based on non-linear programming is considered. The results are compared with the method currently used based on linear programming. The results of the computational simulation show that the non-linear programming is the most suitable optimization method.

Keywords : hydroelectric energy; cascade   reservoirs; optimization; non-linear programming.
